Green List (high evidence)

Spondylometaphyseal dysplasia with cone-rod dystrophy (SMDCRD) is characterized by postnatal growth deficiency resulting in profound short stature, rhizomelia with bowing of the lower extremities, platyspondyly with anterior vertebral protrusions, progressive metaphyseal irregularity and cupping with shortened tubular bones, and early-onset progressive visual impairment associated with a pigmentary maculopathy and electroretinographic evidence of cone-rod dysfunction. At least 3 unrelated, molecularly confirmed, families. Green for this association.

In addition, two individuals reported with bi-allelic LoF variants, and lipodystrophy, fatty liver, severe insulin resistance, and diabetes. Amber for this association.
